HP PAVILION DV5-1214 touch bar LEDs dosent change color

Hello My laptop has 4GB RAM but HP ship it with Vista 32bit (Lame uh) so I installed Windows 7, everything seems to work except the LEDs at the touch bar aint change color. when you press the "mute sound" button it should turn red, but it stays at the same color, the sound get's muted. Anybody knows a fix?
